WlCK-TUBE.

SPECIFICATION forming part of Letters Patent No. 576,447, dated February2, 1897.

Application filed February 24:, 1896- Serial No. 580,478. (No model.)

To all whom it may concern.-

Be it known that I, FRANK P. GLAZIER, a citizen of the United States,residing at Chelsea, in the county of \Vashtenaw and State of Michigan,have invented certain new and useful Improvements in VVick-Tubes, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

The invention relates to an improvement in wick-tubes; and it isembodied in the constru ction hereinafter described,and definitelypointed out in the claims.

In the drawings, wherein like figures of reference designatecorresponding parts in the several views, Figure 1 is averticaltransverse section through the wick-tube. Fig. 2 is the blank from whichthe wick-tube is formed. Fig. 3 is a perspective view of the wick-tube,

showing one end partly open; and Fig. at is a horizontal section throughthe wick-tube just above the plane of the wick-raising shaft.

The wick-tube Ipreferably make from a single piece of sheet metal, asshown in Fig. 2, striking out of one side the housing 1 and from theother side the two parallel ribs 2, with an intermediate curved bearing3, these parts being opposite each other when the plate is bent togetheron a central transverse line, as shown in Fig. 3. In each end of thehousing I secure the bracket 4:, in which the ends of the wick-raisingshaft 5 are journaled, this shaft being provided with suitable toothedwheels 6. The effect of this construction of wick-tube is useful in atwofold manner: First, the ribs serve to strengthen the sheet metal, sothat it does not bend or buckle outward when the thrust of raising thewick comes against it, and, second, it gives a longer and deeperengagement of the teeth of the raising-wheels, thus acting to morepositively raise the wick under all circumstances.

It is evident without further description that the ends of the plate,Fig. 2, are overlapped and soldered or otherwise secured together, orthat the tube may be made of two separate plates of sheet metal, asdesired.

What I claim as my invention is- 1. A wick-tube consisting of a singlepiece of metal bent to form a tube one section having the longitudinalhousing 1, and the directly opposite side section being bent inwardparallel with the housing to form an inwardlyextending longitudinal rib,and a wick-raiser between the housing and rib, substantially as setforth.

2. A wick-tube comprising two flat sides, one of which has alongitudinal depression in its inner face, and the directly oppositeside section having longitudinal flanges bent up from the metal of theside and arranged parallel with the depression, and a wick-raiserinterposed between the depression and the flanges, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.
